The object of the present invention is to provide a simple attachmentfor typewriters whereby the underscoring of words or phrases or theformation oi leader lines will be tacilitated. The invention also hasfor its object the provision of means whereby lines may be made easilyand rapidly transversely of the platen of the typewriter to extendvertically upon the sheet of written matter is or the lines may be drawnobliquely upon the sheet so that any desired formation may be producedto entirely enclose matter which is to be emphasized or to form captionsor toconnect any desired words or phrases. The invention also seeks toprovide a mechanism for the stated purpose which will be compact, willnot interfere with the usual operation of the typewriter in any way andwhich will be set in working position by pressure upon so a key disposedat or adjacent the keyboard of the machine. The several stated objects,and other objects which will appear incidentally in the course of thefollowing description, are attained in such a mechanism as isillustrated in the accompanying drawings, and the invention resides incertain novel features which .will be particularly pointed out in theclaims.

In the accompanying drawings:

The typewriter, indicated 'as an entirety at 1, may be of any well knownor approved form and is equipped with thevusual platen 2 over which thesheet for receiving'the typewriting is disposed and past which it is fedin the operation of the typewriter. In car-' rying out the presentinvention, there is' pro- 1930. Serial No.'465,431.

vided a marker 3 which may be a pencil or a stylus and which is providedwith a marking point e adapted to impress upon the typewritten sheet ahorizontal, a vertical or an oblique line when properly manipulated. Themarking point 4: in the present instance is shown as fitted in the endof a holder 5 and extending axially therefrom through a retaining cap 6,the holderfi being slidably fitted within a tubular casing '4' housedwithin which is an expansion spring 8 bearing upon the holder so as toproject the same from the casing. At its forward end the casing isconstructed with a ball 9 fitting within a spherical socket 10 and heldtherein in a set position by a thumb screw 11 mounted in the wall of thesocket and hearing against the ball, as clearly shown in Fig. 5. Alocking projection 12- is formed on the upper side of socket 310 and arack 13 is engaged with said projection to hold'the marker in a setposition against the force of the spring 8, as will be understood uponreference to Fig. 5, the rack being formed on the lower edge of a bar 14which is secured at its front end to the holder 5 and projectsrearwardly therefrom through a guide loop or keeper 15 formed on thesocket 9. The holding bar 14 is equipped with an enlargement 16 at itsfront end which constitutes a handle and in the keeper or guide loop 15is secured a leaf spring 17 which bears upon the bar so that the rack 13will be held in engagement with the projection 12 to lock the marker inits adjusted position. The socket 1.0 is formed at the upper end of anarm 18 which has a hub or sleeve 19 formed at its lower end and saidsleeve or hub is fitted around and secured to a rock shaft 20 which ismounted at the front of the typewriter in any convenient manner. Thedrawings show the rock shaft mounted within a bore formed in a bar 21which is a fixed part of an ordinary typewriter frameand has marginstops 22 mounted thereon. This arrangement is convenient and avoids theaddition of extra parts to the machine but, of course, the rock shaftmay be otherwise mounted, provided its allotted functions may be served.The bar 21 is provided at its center with a slot 100 or opening 23 toaccommodate the sleeve or hub 19, and the arm 18 and the hub are securedin a set position by a set screw or bolt 24 mounted in the hub andbearing against 5 the rock shaft, as will be understood. At the righthand end of the rock shaft 20, I secure thereto a crank arm 25 which isdisposed exteriorly of the typewriter frame and normalprojectsdownwardly and rearwardly 1 fi om the rock shaft, the rear end of thecrank arm being curved eccentrically, as shown at 26, and provided withan upwardly projecting finger or extension 27 to provide a track for aroller 28 at the end of a presser bar or arm 29. The crank arm 25 isnormally held in a raised position by a retractile spring 30 attachedthereto and to the typewriter frame at a point above the arm, as bestshown in Fig. 2, and this spring obviously serves to maintain engagementbetween the track of the crank arm and the roller 28. The presser arm orbar 29 is secured upon a vertically disposed rod 31 which is slidablymounted in suitable bearings and guides 32 on the side of the typewriterframe and is equipped near its lower end with a lateral stud or pin 32',said stud being engaged in the forked end 33 of a rocking arm 34 whichis fulcrumed between its ends upon the side of the typewriter frame andis yieldably held in its normal position by a retractile spring 35 whichis attached to the rocking arm at the rear of its fulcrum and alsoattached to some fixed point of the typewriter frame above the rockingarm, as shown at 36. The front end of the rocking arm 34 is providedwith a depending lug or tooth 37 which is op-, posed to and adapted toride on a similar lug or tooth 38 upstanding at the rear end of an anglelever 39 which is fulcrumed at its angle upon the side of the typewriterframe adjacent the front of the keyboard, the front arm of this leverextending upwardly and terminating in a key or push button 40, as shown.

The mechanism thus far described is sufficient to effect marking oflines upon the typewritten sheet, but in order that the work may befacilitated, I provide means whereby the typewriter carriage may bereleased to be moved backward so as to facilitate the work. To this end,the vertically disposed reciproeating rod 31 is extended above thepresser arm 29 and is then bent laterally, as shown at 41 in Fig. 3, topass outwardly beyond the typewriter frame a sufiicient distance toaccommodate the extreme movement of the carriage, the carriage beingindicated at 42 in Fig. 1. From the lateral extension 41, a shortvertical connecting portion 43 rises and from the upper end of thisshort vertical portion a rod 44 extends inwardly over the carriage andmay be provided at its inner extremity with an abutment or stop 45 ofany convenient form. The upper member 44 passes over the escapementrelease lever, indicated at 46, to bear. thereon so that when a downwardimpulse is imparted to the rod 31 the escapement lever will be releasedand the carriage may then be moved freely in either direction. The stop45 is preferably in the form of a lateral lip or lug at one end of astem or shank 47 fitting within a socket formed in the end of the rodmember 44 and held therein by a set screw 48, as shown in Fig. 3, thisarrangement permitting the stop to be adjusted so as to conform to anygiven circumstances. To reduce frictional wear, a roller 49 may bemounted upon the escapement lever 46 under the rod 44 so that there willbe no interference with the free movement of the typewriter carriage.

The marker 4 obviously is normally out of contact with the sheet oftypewriting and a very slight movement will sufiice to bring it intocontact with said sheet. In order that the sheet may be held smooth andfirm when the marker 4 is in contact therewith, presser members 50 areprovided upon the holder 5 and extend from the opposite sides of thesame, these presser members being resilient arms equipped with rollers51 at their free ends to bear against the sheet of paper in an obviousmanner.

It is thought the manner of using the device will be readily understoodfrom the foregoing description, taken in connection with theaccompanying drawings. The typewriter is operated in the usual manner totranscribe the work. When it is desired to underscore or overscoreportions of the typewritten matter or to connect portions of the same,the key 40 is pressed downwardly thereby rocking the angle lever 39 and,through the engagement of the lugs or teeth 38 and 37, oscillating therocking arm 34 so that its rear end will be moved downwardly, as shownby the full lines in Fig. 2. The downward movement of the rear end ofthe arm 34 will obviously be imparted directly to the vertical rod 31and the presser arm 29 will, consequently, ride downwardly with respectto the crank arm 25 so that said arm will be swung downwardly and theshaft 20 rocked to shift the marker from the position shown by dottedlines in Fig. 2 to that shown by full lines so that the marker point 4will bear upon the paper. At the same time that the marker is thus movedrearwardly against the typewritten sheet, the upper extension 44 ,iscaused to press downwardly upon the typewriter escapement release lever46 so that the carriage will be released and if it is not restrained itwill move quickly towards its initial position and, consequently,

a line will be drawn horizontally across the sheet. Upon reference toFig. 1, it will be noted that the marker is located at the center of theescapement scale upon the typewriter, and it will be understood that themovement of the carriagemay be controlled manually by the operator sothat the marker will be set to begin the line at a desired point andalso controlled to terminate the line at the desired point. The markerwill remain in contact with the typewritten sheet as long as the key 40is depressed and when said key is released the parts will be returned tothe initial positions indicated by the dotted lines in Fig. 2 under theinfluence of the springs 30 and 35, as will be understood. While thecarriage is moving across the machine, the platen may be rotated and asa result of this action an oblique line will be drawn upon the paper. Ifit be desiredto make avertical line, the car riage is shifted to thedesired point, whereupon the key 40 is depressed and the platen thenrotated through the are necessary to inscribe a vertical line of thedesired extent.

It will thus be seen that lines of any desired arrangement may be madeupon the type- I written sheet with facility and speed and withoutrequiring the operator to do any unnecessary or laborious work. Thearrangement is very simple and compact and is not apt to get out oforder.

Having thus described the invention, I.
